Description
1-Way stopcock capillary NS 12,5 bore 1,6 mm is a precision laboratory glass stopcock intended for controlled fluid handling in analytical and preparative work. It combines a solid ground NS plug with capillary ends and a defined bore of 1,6 mm, giving a compact single-way shut-off suitable for fine tubing and glass apparatus. The NS 12,5 joint follows common laboratory ground-joint practice and the design is specified to DIN 12541, supporting interchangeability with matching glassware. Capillary connections help keep dead volume low where small sample streams or reagent lines must be opened and closed reliably. Supplied as one piece with a net weight of 0,046 kg, this stopcock from manufacturer Witeg is produced in Germany for everyday use among valves, conical stopcocks and shut-off fittings. Typical applications include routing liquids or gases in research, quality-control and teaching laboratories that require a durable solid-plug capillary stopcock with a clearly defined bore and standard joint size.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about Stopcock ST 12/1,6
What is this article?
Stopcock ST 12/1,6 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
